The Smartest Race

No, I'm not a racist, nor am I Caucasian, but I've been reading ramblings that tend to suggest that the two "smartest" races on the planet are the Chinese and Indians. From what I've read, this is mostly based on IQ tests and universal academic performance. I believe this goes under genetics, but which group(s) do you guys think has grown to be intellectually superior and why?

Japanis are industrious, I'd responds with the overall mental status, even thou I am a middle easten faggot I will go with the ammaricans, dispite of their reputation of being wild ballucks monkeys.
